<u>If evolution is based upon genetic diversity, it means that evolution in organisms that only reproduce by mitotic division will depend largely on the frequency of random mutation of genes.</u>
The only way that genetic diversity can occur between daughter cells formed from mitosis is if mutation takes place. Mutation general means a sudden change to the gene sequence of an organism.
Without mutation, evolution in mitotic organisms will be non-existence because there are no new genes or alleles being introduced into the gene pool.
